Katherine Heigl‘s neighbors have sprung to her defense after police were forced to interrupt her hot tub hubbub with hubby Josh Kelley.

As RadarOnline.com was first to report, two cops were confronted with an arresting sight — Heigl in a barely-there bikini — when they arrived at the couple’s $2 million mansion in Los Angeles, after receiving a noise complaint.

One neighbor, who did not want to be identified, told RadarOnline.com, “I’m more noisy than her. She and her husband are not a problem, and I wouldn’t be surprised if the paparazzi probably called the police.”
